Abstract (en)

Organosilicon compounds with triazine groups of formula AaRbXcSiO(4-a-b-c)/2 (I) are new, where R = H or monovalent optionally substituted hydrocarbon; X = halogen or -OR<1>; R<1> = alkyl optionally substituted with an ether O atom; a = 0-1 (0.01-1); b = 0-3; c = 0-3; A = group of formula (II); R<2> = optionally substituted alkylene; Y = H, optionally substituted alkyl or -OR<1>; Z = X, -NR2, -(O)CR or -SR; and a+c ≤ 4 (0.1-4). Each polymer molecule contains at least group A with one or more halogen atoms in it. Also claimed are (i) the preparation of (I) by reacting organosilicon compounds of formula BaRbXcSiO(4-a-b-c)/2 (III) with an optionally substituted cyanuric halide in the presence of a base; and (ii) equilibrium reactions of (I). In (III), R, X, a, b, c = as above; B = group of formula (IV); and R<2>, Y = as above.
